【摘要】 为满足交通低干扰、结构少损坏的需求,快速、无损探识公路病害成为公路性能检测的发展趋势。该文以综合判识为原则,在分析现有各种无损检测手段技术特点的基础上,建立了FWD(落锤式弯沉仪)和探地雷达为组合的隐形病害无损检测方法,并通过数值模拟和室内试验,针对路基脱空病害,验证了该方法的可行性。更多还原

【Abstract】 In order to satisfy the demand of low traffic interference and little structure damage,the rapid and nondestructive detection of highway fault becomes the development tendency of highway performance detection.Based on the principle of comprehensive identification and the analysis of technical characteristics of various nondestructive detection methods,the hidden fault nondestructive detection method combined with FWD(falling weight deflectometer) and ground penetrating radar is established,and is tested by numerical simulation and laboratory experiment.The validating conclusion shows that this method is feasible for the emptying fault of roadbed.更多还原
